A spreader vehicle, particularly for agricultural use in handling farmyard manure and slurry material ranging from free-flowing liquid to solid consistency, includes a body having one or more discharge openings in a lower part and conveniently to one side of the body, with a rotating impeller immediately outside the opening(s) for broadcast distribution of the material and a feed rotor, for example a large diameter auger, within the body and rotating in close proximity to its floor and at least the lower part of an opening for controlled feed of non-free flowing material through that opening. Preferably the impeller and the feed rotor are driven in the same direction of rotation about parallel horizontal axes so that the material is fed beneath both those axes, and the rate of passage of material through the opening(s) is regulated by a sliding door(s) or other closure means.
